- Defined in lab/util/Random.ts:24

getSeed

getSeed(): number
Returns the seed of the random number generator.

Returns number
the seed of the random number generator
- Defined in lab/util/Random.ts:29

nextFloat

nextFloat(): number
Returns random floating point number in range [0,1].

Returns number
random floating point number in range [0,1]
- Defined in lab/util/Random.ts:34

nextInt

nextInt(): number
Returns next random integer in range 0 (inclusive) to modulus (exclusive).

Returns number
next the pseudo-random number
- Defined in lab/util/Random.ts:39

nextRange

nextRange(n): number
Returns random integer in range 0 (inclusive) to n (exclusive).
Parameters

random integer in range 0 (inclusive) to n (exclusive)
- Defined in lab/util/Random.ts:45

randomInts

randomInts(n): number[]
Returns an array of integers from 0 to n-1, in random order.
Parameters
- n: number
  the size of the array to create

setSeed

setSeed(seed): void
Sets the seed of the random number generator; must be an integer between 0 (inclusive) and modulus (exclusive).
Parameters
- seed: number
  the seed to start the random number generator with
